Abstract: Using a scanning tunneling microscope (STM), topographic and spectroscopic measurements at low temperatures T $\sim$ 20 K were carried out on a buckapyper-sample, which consists of single wall nanotubes (SWVTs). Topography measurements show how individual SWNTs aggregate to microbundles which in turn aggregate to ropes. The network of ropes forms the buckypaper felt. Individual nanotubes within larger bundels could be resolved. The electroic structure of the buckypaper sample was investigated using I(V) spectroscopy on individual nanotubes in the buckypaper. The analysis of the data reveals the bandgaps of the individual SWNTs. The buckypaper consists of 35 % metallic SWNTs, 15% near gap SWNTs (0 < E$_{gap}$ < 0.3eV) and 51% wide gap SWNTs (E$_{gap}$ > 0.5eV). Using theoretic models we deduce the SWNT diameter distribution from our electronic structure data.
